They ask you mostly softball questions, primarily the patriotic type ones so just answer like you bleed red white and blue and that you're fired up and they'll accept it. Such as "Why do you want to serve in the USAF?"

What kind of positions are you interested in? Is there a particular job you are interested in? How old are you? What is your GPA? Have you graduated high school (if so, from where)? Are you married? Kids? What are your future goals? Are you currently working? Who is your employer? Do you have any college degrees or certs? Have you ever been arrested for a felony or for substance abuse? Have you ever taken drugs, if so, what? Do you have tattoos? Those are the top questions I remember. If you have not graduated high school, they do have programs for you.
